Product Description
industrial multi-panel steel folding door is the ultimate solution for ultra-wide openings where space, security, and insulation are critical. Unlike traditional sliding or sectional doors, our accordion-style folding system is engineered to maximize your clear opening while minimizing space occupation.
Constructed with a heavy-duty galvanized steel frame and PU foam insulated sandwich panels, this door provides exceptional thermal efficiency (U-value < 0.33 W/m²K) and sound reduction. The reinforced structure is tested to withstand Class 10-12 wind loads, making it perfect for coastal areas and open-air hangars.
Key Features:
Multi-Leaf Accordion Folding: Panels fold neatly to one or both sides, requiring minimal side wall space.
Robust & Insulated: Double-sided galvanized steel with a high-density polyurethane core ensures durability and energy savings.
All-Weather Performance: Hot-dip galvanized hardware and weather-resistant powder coating prevent rust and corrosion.
Customizable: Available in any width or height, with optional pedestrian doors, observation windows, and RAL colors.
Applications:
Aircraft hangars, fire stations, train depots, logistics warehouses, heavy industry workshops, and exhibition halls.
Frequently Asked Questions:
-
Q: What is the main advantage over a sliding hangar door?
A: A multi-panel folding door only occupies about 1/3 of the side wall space when open, compared to a sliding door which needs an equal amount of space. It also offers better sealing and insulation.
-
Q: Can this door withstand strong winds?
A: Yes, our standard design reaches Class 10 wind resistance, and we can reinforce it up to Class 12 for typhoon-prone areas.
-
Q: Is the door insulated?
A: Absolutely. We use 50mm or 77mm thick PU foam core panels that provide excellent thermal and sound insulation.
-
Q: What happens during a power outage?
A: The door comes with a manual chain crank, allowing you to open and close it easily without power.
